A communication method and a terminal and a base station adapted to the method are provided. The communication method of a terminal includes: receiving a message containing information regarding a semi-persistent scheduling (SRS) configuration from a base station; determining whether a sub-frame configured with a non-adaptive re-transmission is identical to a sub-frame configured with an uplink grant according to the SPS configuration; and when: a sub-frame configured with a non-adaptive re-transmission is identical to a sub-frame configured with an uplink grant according to the SPS configuration; and the terminal does not have data to be first transmitted via the sub-frame configured with an uplink grant according to the SPS configuration, performing the non-adaptive re-transmission.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The method of claim 1, wherein the uplink grant is addressed to a cell-radio network temporary identifier (C-RNTI).
3. The method of claim 1, wherein the uplink grant is associated with a configured grant.
4. The method of claim 1, wherein the MAC PDU is not generated, in case that the uplink grant exists, and in case that the MAC PDU to be generated does not include uplink data and includes the Padding BSR.
6. The terminal of claim 5, wherein the uplink grant is addressed to a cell-radio network temporary identifier (C-RNTI).
7. The terminal of claim 5, wherein the uplink grant is associated with a configured grant.
8. The terminal of claim 5, wherein the MAC PDU is not generated, in case that the uplink grant exists, and in case that the MAC PDU to be generated does not include uplink data and includes the Padding BSR.
10. The method of claim 9, wherein the uplink grant is addressed to a cell-radio network temporary identifier (C-RNTI).
11. The method of claim 9, wherein the uplink grant is associated with a configured grant.
12. The method of claim 9, wherein the MAC PDU is not generated, in case that the uplink grant exists, and in case that the MAC PDU to be generated does not include uplink data and includes the padding BSR.
14. The base station of claim 13, wherein the uplink grant is addressed to a cell-radio network temporary identifier (C-RNTI).
15. The base station of claim 13, wherein the uplink grant is associated with a configured grant.
16. The base station of claim 13, wherein the MAC PDU is not generated, in case that the uplink grant exists, and in case that the MAC PDU to be generated does not include uplink data and includes the padding BSR.
